Summary: Plastic pollution is a growing concern as plastic particles are found in the atmosphere, land, and water due to various pathways. Recent research has shown that plastic particles are present everywhere, from the Arctic to the Antarctic. The ingestion of plastic by all living organisms is natural given the widespread microplastic pollution in the environment. The accumulation of microplastics poses a threat to living beings, and its consequences are still being studied. This review highlights the research conducted by scientists on microplastics in different drinking water sources, emphasizing the need for a uniform protocol for analyzing microplastics quantitatively and qualitatively. It is crucial to address and expand research on microplastic pollution as an ongoing environmental concern.

Summary: Researchers synthesized Au/Ag-doped CZTS nanocrystals as photocatalysts for wastewater treatment. The nanoparticles can amalgamate under normal temperature and pressure conditions, eliminating the need for high-end equipment. Au/Ag doping slightly shifts the absorption range of CZTS nanoparticles to a desirable state for photocatalysis. The synthesized nanoparticles exhibit high stability and recyclability, and have been successfully applied for the reduction of real textile waste and heavy metal (Chromium VI).

Summary: Ag2O was introduced to ZnS for the first time to form a novel ZnS/Ag2O composite photocatalyst, showing high catalytic activity in degrading methylene blue. The composite degraded 92.4% of methylene blue in 50 min, outperforming ZnS and Ag2O which only degraded 31.9% and 68.8% respectively. Enhanced photocatalytic activity was attributed to the composite structure, facilitating carrier separation and extending light response range. The ZnS/Ag2O composite is promising for degrading organic pollutants in water.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.
